After I Transmigrated into a Book, the Supporting Lady Was Stunning

Bai Yixi accidentally entered a book before she was even born, and spent her childhood causing trouble. What?! The frail little boy who treated her like an enemy when they were kids is the male lead! What?! The boy she bullied until he cried is the second male lead! What?! The girl whose candy she stole as a child is the female lead! And on top of that, she’s a cannon-fodder supporting character. Bai Yixi was left utterly bewildered, then promptly ran away. Three years later, she came back to start high school. Wait, Male Lead, aren’t you supposed to be at No. 11 Middle School next door? Wait, Second Male Lead, aren’t you supposed to be sweetly supporting the female lead? Wait, Female Lead, why are you looking at me with jealousy? Male Lead: “Is it really that hard to love me?” Second Male Lead: “Without you, what good is this championship to me?” Bai Yixi: “Where did my original, authentic male and second male leads go?!” Bai Yixi tried to run away again, but a certain powerful man trapped her in his arms. His eyes were dark red, and a cool, aloof smile touched his handsome face. “Run again, and I’ll die right in front of you.” Bai Yixi shouted: This isn’t the male lead I know! The male lead in the novel wasn’t obsessive and unstable! Watching the male lead grow darker by the day, Bai Yixi wisely gave in. “Come on, give me a kiss. Don’t be mad!” P.S. 1. The male lead has dissociative identity disorder. 2. This isn’t an ordinary world: it has supernatural and fantasy elements.
